From 47af5518526d435d0d56a329a578f240e86eb678 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Mon, 4 Dec 2006 15:41:07 +0100 Subject: [PATCH] [S390] cio: Use device_reprobe() instead of bus_rescan_devices(). In io_subchannel_register(), it is better to just reprobe the current device if it hasn't a driver yet than to rescan the whole bus.
